ABSTRACT:
The principles of the present invention provide for using directional antennas to adaptively communicate in a wireless mesh network. A number of infrastructure components are included in a wireless mesh network environment. Each infrastructure component includes an omni-directional antenna and one or more directional antennas (e.g., electronically steered phased array antennas) that can be used to communicate with other infrastructure component and wireless devices. Directional antennas can utilize one or more directional beams that can be directed towards an infrastructure component or wireless device to communicate with the infrastructure component or wireless device. Infrastructure components can adapt to communicate with the same destination through different intermediary infrastructure components. Since the signal strength of a directional beam can be greater than that of an omni-directional antenna of the same gain, infrastructure components can be separated by greater distances.
